Sounds normal, how many k's on the car?
Adjust throttle cable, clean throttle body, clean everything, that's all you can do.

Clean injectors. Fuel filter. Etc.

After resetting ecu, should normalize after time.



With revs dropping when you stab the throttle quickly, you will always get idle drop before rpm rise.

Reason for this is delay from mechanical throttle cable.
If drive by wire, no delay, is better.

Cable puts more air in, takes a fraction of time for sensors and ecu to adjust fuel.

My problem - If you are driving around with the car cold and put the clutch in (like stopping at the lights) the revs drop past the proper idle point and the car almost cuts out. When warm, this prob is gone. Instead, when you jab the throttle quickly from idle (like for a quick take off), the revs initially drop (to like 500rpm or less) before going up as they should. The actual idle rpms are fine (~830 rpm warm).
